(1) a request on all parties if the land or property belongs to a party, or

If the identity or address of the nonparty is unknown and cannot be obtained through reasonable diligence, the court must permit service by means other than those specified in Rule 21a that are reasonably calculated to give the nonparty notice of the motion and hearing.

(b) Time, place, and other conditions; The request for entry upon a party's property, or the order for entry upon a nonparty's property, must state the time, place, manner, conditions, and scope of the inspection, and must specifically describe any desired means, manner, and procedure for testing or sampling, and the person or persons by whom the inspection, testing, or sampling is to be made.

3.

Otherwise, the responding party need only produce the data available in the ordinary course of business in reasonably usable form.

4. The rule clarifies how the expenses of production are to be allocated absent a court order to the contrary.

5. The obligation of parties to produce documents within their possession, custody or control is explained in Rule 192.3(b).
